Export a project as MusicXML
MusicXML is an XML-based music notation file format, supported by many notation and music OCR applications and some music production applications. You can freely redistribute the MusicXML DTDs and XSDs used with MusicXML under the MusicXML Public License.
Many score writing programs (including Finale, Sibelius, and MuseScore) and Music OCR programs (including SmartScore and PhotoScore) can open and display MusicXML files. Some music sequencer programs (including Cubase, SONAR, and Rosegarden) can also open these files.
